Using OnClick event on a Submit Button

[StargazeR82]

I'm using ASP/VBScript. I want to put a form value into an ASP Session variable when the submit button on the form is clicked. Is this possible? I thought that the onclick event had to be executed on the client side to work and therefore ASP code that is executed on the server side wouldn't have access to it. Am I even close to being correct?

Yea, it wouldn't be possible but you can do something like onclick=formname.sessiondata.value='blah' then have a hidden text field named sessiondata. When you run the form action script, have it evaluate sessiondata and if it's not null, then you have to set your session variable. That's how I'd do it. Almost all of my pages work something like that. I have one ASP file and when the user clicks a button, link or whatever it sets a hidden "mode" value to tell the index.asp what section to run then "submode" as needed, etc.
